How long to save $500,000 in a 401k?

Maxing a 401(k) at $23,500/year ($1,958/month) and earning 7% average annual returns, you'd reach $500,000 in about 13.7 years. With employer matching, the timeline shrinks further — a 50% match on up to 6% effectively adds $3,000-$6,000/year to your contributions.

Is $500,000 enough to retire on?

$500,000 at a 4% safe withdrawal rate generates $20,000/year. Combined with Social Security income ($15,000-$25,000/year for most Americans), that creates $35,000-$45,000 in annual retirement income, which is workable in low cost-of-living areas but tight in high-cost metros. Most planners recommend $1M-$2M for comfortable retirement.

What net worth is $500,000?

$500,000 in net worth puts you above the 75th percentile of American households under 55. It represents meaningful financial independence progress — enough to generate ~$35,000/year at a 7% investment return.

How Long Does It Take to Save $500,000?
